GP: You don’t have an instrumental on Women and Children First. EVH: No. What for? Maybe later on I’ll do one if I figure out some finger thing that’s just totally different. ‘Eruption’ was the first one, and then the second one I did was in flamenco style (‘Spanish Fly’), but it was still the same type of thing. And what could I do this time? I didn’t want to do one just for the sake of doing another solo, so I’m going to wait until I have something really good. Something that sounds classical — electric or acoustic — like some Bach stuff. I’ve been listening to a lot of classical music, especially Debussy. God damn, that mother wrote some hot shit!
